In a modest workshop somewhere between curiosity and necessity, a maker known as ProjectsInFlight accomplished what commercial pricing had long made unthinkable for most: converting a scanning electron microscope into a transmission electron microscope using hand-machined aluminum and iterative ingenuity. The distinction between these two instruments is not merely technical — one reads surfaces, the other reads through, and that difference is the difference between shadow and substance. By solving a 14-millimeter clearance problem with patience and a lathe, this project quietly challenges the
